Background technology
It generally is by pincers worker workpiece to be carried out the circumference line earlier that prior art is equidistantly holed on the excircle of round piece, going up drilling machine again holes, this method not only production efficiency is low, operating technology to the operator also requires height, but also exist spacing of wells error big, general accumulated error reaches 2 millimeter, has had influence on the quality control of brake drum balance pipe spacing; Also having a kind of method is to adopt rotating disk anchor clamps or revolution turntable that workpiece is installed, although this method can improve the revolution positioning accuracy, but have anchor clamps cost height, the adjustment of workpiece, loading and unloading capacity complexity are not suitable in bulk the brill system of the isometric balance holes of brake drum is produced.
Summary of the invention
It is big and then influence the technical problem of the production technology quality of brake drum that the boring grab of the isometric balance holes of brake drum provided by the invention has solved the spacing of wells error that exists when prior art is bored isometric balance holes on automobile brake drum.
The present invention overcomes the above problems by following scheme:
A kind of boring grab of isometric balance holes of brake drum, comprise the L bracket that is fixed on the radial drill base, the roller that fixedly installs on riser one side of L bracket is hung drum, hang the movable brake drum that is provided with on the drum at roller, be movably set with vertical stroke piece of T shape in the upper end, riser another side of L bracket, the riser of vertical stroke piece of T shape is provided with vertical guide groove, between the riser of vertical guide groove and L bracket, be provided with first set bolt, by regulating the position of first set bolt in vertical guide groove, vertical stroke piece of realizing T shape longitudinally guide groove in the upper and lower displacement of vertical direction.On the top board of vertical stroke piece of T shape, be set with the infeed stroke piece of horizontal direction, end at the infeed stroke piece is provided with horizontal guide groove, laterally in the guide groove second set bolt is being set, this second set bolt links together the top board of vertical stroke piece of infeed stroke piece and T shape, realizes the left and right displacement of infeed stroke piece along the horizontal direction of horizontal guide groove by regulating the position of this second set bolt in horizontal guide groove.The other end at the infeed stroke piece is provided with the boring guide pad, the boring guide pad is arranged on the top of brake drum, and be provided with along the excircle direction of brake drum, the drill bit that the boring guide pad is provided with radial drill passes through the hole, be respectively arranged with pin shaft hole, the central axes of the isometric balance holes of the central axis of pin shaft hole and drilled brake drum in the left and right sides of drill bit by the hole.In pin shaft hole, be provided with pin sleeve, in the pin sleeve of pin shaft hole, be movably set with bearing pin, in the movable equally spaced balance pipe that is inserted on the brake drum that has bored in the top of bearing pin, end at bearing pin links together by handgrip nut and bearing pin handgrip, with insertion and the taking-up that makes things convenient for bearing pin.The boring guide pad can be fixed on an end of infeed stroke piece by the 3rd set bolt, only need unclamp the different boring guide pad of the 3rd set bolt replacing when holing for the automobile brake drum of different size and can realize.
The present invention has improved the spacing of wells precision of the isometric balance holes on the automobile brake drum, guarantees the production technology quality of automobile brake drum, and mechanism is simple to operate, changes easy to maintenance.
